Return to cmd-server-info.c CVS log

Up to [local] / src / usr.bin / tmux

Change session and client activity and creation time members to have more
meaningful names.

Also, remove the code to try and update the session activity time for the
command client when a command message is received as is pointless because it
des not have a session.
